Defending Against Cache Based Side-Channel Attacks

Abstract

Cache based side-channel analysis is a new technique that uses the application
specific behaviour of cache memory to leak secret information about a running
algorithm to the attacker. Two complementary methods have been proposed which
describe how such attacks could be mounted but there has been little work on
how one might defend devices against the resulting security breaches. This
paper surveys a number of hardware and software based approaches to defending
against such methods of attack and evaluates each using simulated results.
